1.6 Safety precautions
Each device is manufactured in compliance with the provisions of Council Directive 93/42/EEC
(MDD) and 2007/47/CE concerning medical devices. Always observe the following precautions:
Warning
When disconnecting the optic fiber from the device, always cover the connector with the
special protection cap. Otherwise the unit may be permanently damaged. Make sure that no
dust or dirt can enter the connections of the optic system.
Caution
Any use of the controls or setting options in a manner other than the one described here may
lead to a dangerous exposure to radiation. Manufacturer is not responsible for damages
caused to the non-correct use of the device or to the disrespect of the instructions and caution
indicated in the present manual.
Caution
Never place your finger or any other objects in the optical connectors. This could cause
damage to the optical instrument.
Caution
Switch the device OFF immediately in case of an emergency. To do this, press the “LASER
STOP” button below the touch screen on the front side of the control unit.
Warning
Observe all labels on the device.
Warning
Operation of this laser unit by unauthorized persons must be prohibited in order to prevent
incorrect or improper use. Laser equipment not in use must be protected against unauthorized
access. This can be achieved for example by switching off the laser unit after use, so that the
electronic access key must be entered prior to further operation.
Warning
Never direct the laser beam toward a person’s eye or thyroid gland. All persons present in the
room (patient, operator and assistant) must always wear the laser protective goggles delivered
along with the device.
Warning
Never use optical instruments such as microscopes, eye loupes or magnifiers together with the
original protective goggles. Otherwise sufficient eye protection can no longer be ensured.
Warning
Oxygen-saturated materials such as cotton wool can catch fire owing to the high temperature
that the unit reaches during operation. Label removers and flammable solutions used for
cleaning and disinfecting the device should be allowed to evaporate before using the device.
Observe fire hazards caused by flammable gases.
Warning
The unit is not suitable for use in the presence of anesthetics that are flammable when in
contact with air, oxygen or nitrogen monoxide.

Operating instructions K-Laser Blue Dental Rev. ZE Page 8 of 72
Warning
Never direct the laser beam toward paper, plastics or objects with dark surfaces. They could
catch fire due to the high temperatures produced by the laser beam.
Caution
Avoid interference between the laser emission and any optical sensors of devices operated in
the vicinity of the device.
Caution
Do not place the unit near heat sources. Do not cover the convection openings for air cooling
on the sides of the unit.
Caution
The device may be operated only by authorized personnel. In order to prevent false or
improper use, the device must not be used by unauthorized persons. Do not write down the
electronic access key somewhere else in order to reduce risk of misuse of the laser by
unqualified persons. Please turn off the unit after the use.
Warning
Set up the laser unit properly and completely before putting it into operation.
Warning
Make sure that the electrical system is equipped with the required devices for protection
against direct and indirect contact (thermomagnetic switches, residual current circuit breakers)
and has been set up by a qualified electrician in compliance with the applicable standards.
National directives regarding electrical installations must be observed.
Warning
Verify that the line voltage corresponds to the voltage indicated on the rating plate of the
adapter or in the technical specifications.
Warning
Do not use the device if a visual inspection shows that it has been damaged.
Warning
If you accidentally spill any liquid on the unit, immediately stop treatment, disconnect the power
cable and contact your local depot or your authorized service center for assistance.
Caution
Never under any circumstances try to disassemble the device. This is limited exclusively to
trained and authorized personnel.
Caution
Switch the device OFF immediately in case of fiber breakage.
Caution
The use of this device close to or over (above or under) other devices must be forbidden
because an improper functionality could happen. If needed to do this, the unit and the other
ones must be maintained under control to verify the correct functionality.
Caution
The device may only be operated with the Sinpro MPU101-106 power supply and the power
cable provided.
Operation with other power supplies may result in failure or destruction of the laser unit and the
use of power cables not provided by Eltech K-Laser can compromise the conformity of the
device regarding emissive requirement and immunity. If any power supply, power cable or
accessory other than the one recommended is used, the approval of the entire unit
automatically becomes void and the warranty expires.
Caution
The use of accessories, transductors or power cables not provided by the manufacturer of the
device, could increase the electromagnetic emission and decrease the electromagnetic
immunity of the device.

Warning
It is recommended not to use the handpiece for therapy in direct contact to skin of the patient,
but to keep distance from the skin and always move it!
Warning
Before therapeutical treatment with the handpiece for therapy, please treat fix points, keeping a
distance of at least two centimetres from the skin of the patient, in particular if you are using
CW (continuous emissions), in order to check the sensibility of the patient and the energy
density, especially if the patient’s skin is particularly brown.
Warning
In case of the use of the handpiece for therapy it is recommended to verify that the part to
treatment not present neo of great dimension or dark zones that could absorb excessive
amounts of energy. In this case protect with dioxide of titanium or zinc the treatment part.
Caution
Laser fume and/or plume may contain viable tissue particulates.
Notice
For the use of handpieces, please read carefully specific instructions and warnings.
